Okay, if greyscale is automatic contrast that is what I have been using all
along.

As Mayrie describes gray scale, it probably is the top choice under
"scanning contrast" which is automatic contrast.  Generally that setting is 
what I
use,
but in situations like the one you describe, the range of automatic
contrast just is not broad enough. 

Unfortunately, today I began to scan a paperback which I got from the
library.  The double l is recognized as a u, t is sometimes recognized as f; as
yet,
I have not been able to find a setting which corrects these recognition
errors.  When they are corrected, other letters become unrecognizable.  I'm not
sure I can remedy this problem.

I just looked. I have a setting labeled color scanning and another one
labeled white on black. Both can be checked or unchecked and right now they are
unchecked
which seems to be the default setting. I saw nothing about greyscale.

Hi Roger,    

I don't use OpenBook, so don't know where to tell you to look for a gray
scale setting exactly.  It should be in your scanner settings menu.  You
should
have options such as, color, gray scale, dynamic, and static.  You may have
either some or all of these as options.  I scan exclusively using gray
scale. 
And doing this, if the results prove to be some that you like will keep you
from having to adjust your scanner brightness every time you switch pages. 
What gray scale does is adjust itself as needed, essentially.  Nope.  I
have no idea how this is achieved.  What I do know is that the results are
much,
much better, in my experience than any other scanner setting.  The
recognition time is longer than with other settings, but less long when you take
into
consideration the amount of time you'd be spending correcting all the
mistakes that you get with other settings. 

Good luck! 

Happy scanning. 

Mayrie

Okay, I just subjected one of those recalcitrant pages to the adjustment of
contrast remedy. I started at 25 which resulted in my being told that I had
a blank page and rescanned it several times adjusting the contrast up in
increments of 25 each time. When I got to 175 I got a fairly decent scan. The
text was a little unclear at the end of the page, but I may be getting the
hang of this. I still want to do a little more experimenting, though, and I
probably will not tackle one of these decrepit old books until I have
finished proofreading the fairly lengthy one I am proofreading now.
